Pharmaceutical/intermediate Wastewater Treatment

Solution：

Pharmaceutical/intermediate wastewater due to the large amount of water first through the MVR or multi-effect evaporation, the resulting high concentrated mother liquor into VESALT scraping plate low temperature vacuum drying crystallization system, under the vacuum low temperature conditions of evaporation and drying, can greatly reduce, remove the waste liquid contains inorganic salts, heavy metals and COD, finally obtain dry solid crystal salt, solid crystal salt moisture content ≤15%. The water vapor in the wastewater condenses to form a distillate, which is collected into a clean water bucket. The water yield can reach 70% ~ 90%, the water quality is clear and transparent, and the distillate can be reused as middle water or meet the discharge standard.

Brief Introduction:

Wastewater Source:

Pharmaceutical wastewater including antibiotic production wastewater and synthetic drug production wastewater, proprietary Chinese medicine production wastewater and all kinds of preparations of the production process of washing water and flushing wastewater four categories.

Wastewater Characteristics:

Due to different drugs, production techniques, different and different, usually has a complex, organic pollutants variety, high concentration, high COD and BOD value and volatile, refractory material, more strong toxicity, etc.

Wastewater Hazards:

Pharmaceutical wastewater is a kind of wastewater that is difficult to treat at present. Due to the complex composition, high organic content, high toxicity, deep color and high salt content of pharmaceutical wastewater, especially the poor biochemical property and intermittent discharge, biochemical treatment process cannot be directly adopted.

Treatment Difficulties:

The wastewater of pharmaceutical factories is usually discharged intermittently, and the type and quantity of products vary greatly, resulting in the great changes in the quality of wastewater, the amount of water and the type of pollutants, which brings great difficulties to the treatment.

In our zero wastewater production and Application center, we have been developing innovative technologies that significantly improve the quality of distilled water for many years. For example, VESALT scraper crystallization technology with special technology can meet all quality requirements through a clever system preparation, so as to obtain clear distilled water and dry solid crystals. This makes our dry at low temperature crystallization system has unique characteristics in the global market.
